Writing on Facebook, Governor Sarah Palin (R-the Internet), argued that “reports of tour demise are greatly exaggerated,” referring to a Real Clear Politics scoop that Palin’s One Nation cross-country publicity stunt has been summarily truncated. We were delighted to see Palin quote Mark Twain, who once addressed a false rumor of his impending demise with the riposte: “The reports of my death are greatly exaggerated.” Looks like someone has an answer ready to go when she’s next asked what she reads. Palin’s excuse for not canceling the non-publicity tour: jury duty. “The coming weeks are tight because civic duty calls (like most everyone else, even former governors get called up for jury duty) and I look forward to doing my part just like every other Alaskan,” she wrote, adding, “I wouldn’t think it to be such a slow news day that, what with numerous wars and serious economic woes concerning Americans, a bus is driving news stories today.” Is that a transportation pun? She is truly cementing her reputation as the Mark Twain of Facebook.com/SarahPalin.
